摘要

在对框架型镁合金压铸件工艺分析的基础上

对其工艺结构进行初步设计;然后使用铸造工艺模拟软件对其充型及凝固过程进行数值模拟

预测了完全凝固后存在于铸件中的缩松、缩孔等缺陷;最后对工艺参数进行了优化。优化后的工艺参数:冲头压射速度为3.3m/s

浇注温度为670℃

模具初始温度为190℃。

Abstract

Process structure was designed for magnesium die casting based on analysis of the process of frame type magnesium alloy castings. The filling and solidification of magnesium alloy in die casting were simulated by the software. Shrinkage porosity （holes） probability in the die casting was forecasted. The results show that the optimized condition is presented as follows: injection speed of 3.3 m/s

pouring temperature of 670 ℃

mold initial temperature of 190 ℃.
